Subject: rt2x00: rt2x00pci_regbusy_read() - only print register access failure once
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3a703ab5fba5b00292c1e7e964783c304f43fef7;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

rt2x00: rt2x00pci_regbusy_read() - only print register access failure once

BugLink: http://bugs.launchpad.net/bugs/1128840

It appears that when this register read fails it never recovers, so
I think there is no need to repeat the same error message ad infinitum.
